背景技术
U.S 4,452,808披露了一种具有选择性D2受体活性的4-氨烷基吲哚-2-酮衍生物。这些化合物可以用于治疗高血压。所述专利提供的化合物之一,即名为4-[2-(二-N-丙胺基)乙基]-2(3H)-吲哚酮,可以用于帕金森病的临床治疗。
EP 281,309提供了在5位有芳基哌嗪基-烷基取代基的吲哚-2-酮衍生物,其可以用于治疗精神疾病。所述专利描述的化合物之一,即名为5-[2-[4-(1,2-苯并异噻唑-3-基)-1-哌嗪基]-乙基]-6-氯-1,3-二氢-2H-吲哚-2-酮通过与D2、5-HT1A和5-HT2受体相互作用而发挥它的活性,可以作为抗精神病药用于临床治疗。
EP 376,607披露了-种在3位由烷基哌嗪基-芳基取代的吲哚-2-酮衍生物,其针对5-HT1A受体发挥其活性,可以用于中枢神经疾病的治疗。
在国际专利申请WO 98/008816中,披露了一种吲哚-2-酮衍生物,其在3位包含取代的烷基-哌嗪基、取代的烷基-哌啶基或烷基-环己基。这些化合物具有亲精神活性。所述专利说明书完全没有提及所述化合物的任何活性谱,作为其应用领域仅仅提到可以治疗抑郁和焦虑。
20世纪技术-社会的加速发展构成了一个强迫人们需要不断适应的环境,这一点,就其不利的方面,可能会导致适应性疾病的发生。适应性疾病在精神或与身心有关的疾病,例如焦虑综合症、应激性疾病、抑郁、精神分裂症、感觉器官疾病、胃肠疾病、心血管疾病和分泌器官疾病的发展中构成了一个重要的危险因素。
为了治疗上述临床类型疾病,人们已经使用了对苯丙二氮系统(例如地西泮)或对中枢5-HT1A受体(例如丁螺环酮或齐拉西酮)具有活性的最广泛的药物。在心身疾病的情况中,抗焦虑治疗经常通过施用具有抗高血压(作用于α1或α2受体)或抗溃疡(H1-受体拮抗剂)活性的药物来补充。
但是苯丙二氮型的抗焦虑剂经常伴随有令人不悦的副作用。它们具有强烈的镇静活性,导致注意力和记忆力的减退以及具有肌肉松弛作用。所述的副作用以有害的方式影响了患者的生活质量,因此限制了这些药物的应用范围。
除了在适应环境期间发生应激以外,现代社会的另一个大问题是人口的快速老化。现代医药科学发展的结果,使得预期寿命增加,而由于年老或者在衰退期间发展而产生的疾病,特别是大量的精神疾病快速和大规模地增加。解决阿尔茨海默病、血管性痴呆和老年性痴呆的治疗已经变成一个社会问题。
基于上述所列举的情况,人们迫切地需要新的和有效的药物,以确保比现在所用的药物更有效地治疗这些疾病。
发明简述
本发明的目的是发展一种药物组分,其具有比现在所用的药物更良好的活性谱,而且没有上述列举的缺点和不希望的副作用,同时可以用于治疗和预防中枢神经和心血管系统的疾病。
本发明是基于如下出人意料的发现:通式(I)的取代的吲哚-2-酮衍生物与现有技术中相似结构的化合物正好相反,显示了与5-HT7和α1受体相当大程度的结合。因此,可以期望它们的适用范围将包括治疗中枢神经和心血管疾病。

本发明是基于如下出人意料的发现:通式(I)的3-烷基-吲哚-2-酮衍生物—与现有技术中相似结构的化合物正好相反—显示了与5-HT7和α1受体相当大程度的结合。
为确定5-HT7受体的亲和力,可以使用人克隆受体。通过从重120-200g的雄性Wistar大鼠的额皮质制品中分离来确定α1受体的亲和力。膜制品的蛋白质含量通过Lowry(1951)的方法来确定。
在5-HT7和α1受体结合研究的过程中,配体为3H-麦角酸二乙酰胺(LSD)(1.0nM)和3H-哌唑嗪(0.3nM)。使用氯氮平(25M)和哌唑嗪(1μM)来测定非特异性结合。根据Reader和Greengras(Reader,T.A.,Briere,R.,Grondin,L.:J.Neural Transm.68,p.79(1987);Greengrass,P.,Brenner,R.:Eur.J.Pharmacol.55,p.323(1979))的方法来进行α1受体结合研究。
IC50是全部结合和非特异性结合的差异为50%时的浓度。在该测定中,认为IC50值小于100nmol的化合物是有效的。实验的结果列于表2和3中。
表1
5-HT7受体结合
实施例号 | IC50nmol |
5 | <100 |
6 | <100 |
8 | <100 |
9 | <100 |

12 | <100 |
从表1和2的数据中可以看出,根据本发明的化合物与5-HT7和α1受体的结合程度非常大。
基于上述实验,可以确定,根据本发明的化合物具有很有价值的治疗谱,它们适合治疗或预防精神和心血管疾病,特别是上述限定的那些疾病。

甲磺酰酯与碱的偶联反应(方法“B”)
缓慢搅拌下,将仲胺的熔化物(12mmoles)加热到120℃,在相同温度下向其中加入甲磺酰化合物(12mmoles)和碳酸钠(1.36g;12mmoles)。让混合物反应1小时,冷却该熔化物,向其中加入乙酸乙酯和水,分离各相。蒸发有机相,将残留的油在较短的柱上进行层析,使用乙酸乙酯作为洗脱液。获得的主要产物即是需要的化合物。
处理方法1:如果通过柱层析纯化的产物经乙醚研磨得到晶体,将其滤出并在己烷和乙酸乙酯的混合物中重结晶。得到的所需的化合物为白色晶体的形式。
处理方法2:如果加入乙醚后基本产物没有结晶,则将其溶解于200ml醚中,滤出少量漂浮的沉淀物,在强烈搅拌下,将溶解于醚中并用50ml乙醚稀释的计算量(1摩尔当量)的氯化氢滴加到纯溶液中。滤出分离的白色的盐,用醚和己烷洗涤,室温下在真空枪中干燥3小时。
处理方法3:如果加入乙醚后基本产物没有结晶并且加入氨化氢没有产生可良好过滤的盐,则将其溶解于100ml热乙酸乙酯中,搅拌下在10分钟内向其中滴加含1摩尔当量二水合草酸的30ml热乙酸乙酯溶液。冷却后白色的草酸盐得到分离。将其在室温下滤出,用乙酸乙酯和己烷洗涤并干燥。
